Did you know? St. Patrick was a real person, but some of the traditions associated with him and the holiday are actually myths. For instance, you’ll often see the four-leaf clover on St. Patrick’s Day. However, according to legend, Patrick used a three-leaf clover, or shamrock, as part of his teachings. Even though it’s possible for a shamrock to grow a fourth leaf, a four-leaf clover is just considered a symbol of good luck.
